We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:
https://discuss.afni.nimh.nih.gov
Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.
The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.
So I need to decide between duration modulation (dmBLOCK) and adding temporal derivatives (SPMG2)? Is it possible to have it both ways?
I've run it both ways, although I now realize that running SPMG2 with RTs married to stimulus onset times will modulate the amplitude, not the shape, of the function.
